Structural Health Monitoring is becoming a point of interest for many institutions and professionals.

We are becoming more and more aware of the importance of understanding if a structure is healthy or not, because aging, deterioration, seismic events or  potential defects in the construction process can lead to serious consequences for human safety.

Asclepius was thought up with the aim of observing changes in the monitored structure and to give us not only the engineering parameters, but also a green or red light,  an intuitive picture of the health of the structure.

Far too often we have an excess of information that we can’t decode or don’t have the time to decode;  in most cases we just want to get a simple answer: yes or no.

Asclepius can make the analysis intelligible even to people who are not in the sector.

The best performances are achieved working in real-time in combination with Atlas or Triton systems, but the software can also be used to analyze off line data.

Asclepius is the result of more than 30 years of engineering experience in the sector.

Asclepius relies on data coming from our sensor network for the operation of its algorithms.

A building where Atlas (or Triton) with LTFB160 or LTME90 accelerometers are installad as suggested by our structural engineers, is the starting point.



The system is connected by WiFi or LAN network, it is strongly recommended that the comunication network has a battery back up in order to handle power cut.

Asclepius runs on a windows PC, the PC can be installed in the local nework or even remotely no matter how distant.


Automatic post-earthquake assessment of structural health

If Asclepius is used as a tool to assess the health of a structure after an earthquake, the acceleration thresholds on the dataloggers (Atlas or Triton) are set during the tuning phase.

When a seismic event exceeds the set threshold, the dataloggers automatically transfer their data to the Asclepius data folder.

As soon as the folder is filled up with new data, Asclepius starts the analysis.


Continuous monitoring of structure health

In this case, dataloggers are configured for automatic transfer of environmental noise data to the Asclepius folder.

Asclepius continuously analyzes the data and sends an alarm if anomalous changes are detected in the monitoring of the structure.


Asclepius’ method of investigation

Asclepius works with two algorithms:

Change in the natural frequency of the structure

This method requires long term environmental noise analysis in the setup/installation phase. This survey is necessary to identify the natural frequency of the structure. Subsequent data analysis, during the monitoring phase aims to  discern potential changes in the natural frequency of the structure.

Inter-floor drift

This technique requires  indepth knowledge of structure design and structural engineering.

The structural engineer must fine-tune the system by entering the maximum safe inter-floor displacements that the structure can handle.

Asclepius monitors the displacements and sends a pseudo-real-time alarm when potential damage to the structure is a risk.


Parameters provided to the user:

  • Peak Ground Velocity (PGV)
  • Peak Ground Acceleration (PGA)
  • Peak Ground Displacement (PGD)
  • Arias Intensity (AI)
  • Significant Duration (SI)​

Calculation of real time displacements and related inter-story drifts (IDR).​

Warnings about potential damage to the structure.

Asclepius is available in different versions:

ASCLEPIUS BASIC:  the easiest  version to use, our structural engineers fine-tune the software unsing the parameters of your structure, you have to supply the structure plans. The software is then ready for use.

ASCLEPIUS PRO: This version is for professionals. The parameters of the structure must be entered in the software by the user.

ASCLEPIUS SERVER: This version can manage multiple licenses on the same PC thus it can monitor different structures.

ASCLEPIUS BRIDGES: This version is specifically optimized for bridge monitoring.
